I generally have to agree with you about the unsigned char* vs char*. It is a problem of the C language that char can be signed and unsigned, and that people, as a result, have used it for storing "shorter_than_short_t"s. What C needs is a distinction between char and int8_t, rendering "char" an unsigned at all times basically and making "unsigned char" and "signed char" illegal types in turn.
